About risk There is no assurance the trust will achieve its investment objective. An investment in this unit investment trust is subject to market risk, which is the possibility that the market values of securities owned by the trust will decline and that the value of trust units may therefore be less than what you paid for them. Recently, an outbreak of a respiratory disease caused by a novel coronavirus, COVID-19, has spread globally in a short period of time, resulting in the disruption of, and delays in, production and supply chains and the delivery of healthcare services and processes, as well as the cancellation of organized events and educational institutions, quarantines, a decline in consumer demand for certain goods and services, and general concern and uncertainty. COVID-19 and its effects have contributed to increased volatility in global markets, severe losses, liquidity constraints, and lowered yields. The duration of such effects cannot yet be determined but could be present for an extended period of time and may adversely affect the value of your Units. This trust is unmanaged and its portfolio is not intended to change during the trust’s life except in limited circumstances. Accordingly, you can lose money investing in this trust. The trust should be considered as a part of a long-term investment strategy and you should consider your ability to pursue it by investing in successive trusts, if available. You will realize tax consequences associated with investing from one series to the next. Common stocks do not assure dividend payments.
